__EVENTTARGET是按键点击回传空 [英] __EVENTTARGET is empty on postback of button click

问题描述

我aspx页面上的按钮

I have a button on aspx page

<asp:Button runat="server" CssClass="sc-ButtonHeightWidth" ID="btnFirstSave" Text="Save" OnClick="btnSave_Click" />

我想获得code事件目标和事件背后的来源做基于它的一些验证。我试着用低于code。

I am trying to get the event target and event source in code behind to do some validation based on it. I tried with below code.

string ctrlname = page.Request.Params.Get("__EVENTTARGET");
string ctrlname = Request.Form["__EVENTTARGET"];
string ctrlname = Request.Params["__EVENTTARGET"];

但上面的所有人都让我空值。如何获得这引起每次回传控制。我做错了点儿以上？

But all the above are giving me empty values. How to get the control which caused postback everytime. Am i doing anyting wrong above?

FYI：我已经尝试过在这个链接提到的解决方案。但其只返回按钮上的文字对我来说。我想buttonID。

FYI : I already tried the solution mentioned in this LINK. But its only returning button text for me. I want the buttonID.
